This kit is consist of three different but reliable antibodies which are specific to the most popular three loading control targets: GAPDH, β-Actin and β-Tubulin, also with three individual package.
Actins are highly conserved proteins that are involved in various types of cell motility and are ubiquitously expressed in all eukaryotic cells(Swiss-Prot Acc.P60709).
Tubulin is the major constituent of microtubules. It binds two moles of GTP, one at an exchangeable site on the beta chain and one at a non-exchangeable site on the alpha-chain (Swiss-Prot Acc.P07437).
Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) catalyzes the phosphorylation of glyceraldehyde-3-phosphate during glycolysis. Though differentially expressed from tissue to tissue, GAPDH is thought to be a constitutively expressed housekeeping protein. For this reason, GAPDH mRNA and protein levels are often measured as controls in experiments quantifying specific changes in expression of other targets. Recent work has elucidated roles for GAPDH in apoptosis, gene expression, and nuclear transport. GAPDH may also play a role in neurodegenerative pathologies such as Huntington and Alzheimer diseases (Swiss-Prot Acc.P04406).
